This is my own explanation:
Explanation:
It is important to know the mixtures you input together because you may determine the type of substance you produced from different elements and several combinations of matter. This assists in identifying your specific substance.
Answer:
a. Kenya's growth seems to be a large population influx, an increase in the pre-reproductive stage.
b. There is a decrease in the younger generation, meaning that the reproductive part of the population is more than the pre-reproductive part. Which means less of an incline in population.
c. You can see the differences within the countries, that the growth rate in Kenya is extremely high, the United States more moderate, while Germany is somewhat even throughout. Germany is not growing much in comparison to Kenya.
The element that will have the lowest electronegativity is an element with a small number of valence electrons and a large atomic radius.
Electronegativity of an element is the ability or power of that element in a molecule to attract electrons to its Valence electrons. The following are the properties of electronegativity:
- It increases across a period from left to right of the periodic table,
- It decreases down the periodic table groups
- Group 1 elements are the least (lowest) electronegative elements. These elements have the lowest valence electrons with a large atomic radius.
- Group 7 elements are the most electronegative elements.
Atomic radius of elements increase down a group because of a progressive increase in the number of shells occupied by electrons which increases the size. But it decreases across a period because electrons are accommodated within the same shell leading to greater attraction by the protons in the nucleus.
